When championship golf comes to San Francisco, the venue is bound to be the Olympic Club. As a consequence, the highly selective San Francisco Golf Club has had no reason to try to develop a championship course of its own, being so close to the Olympic, and its vintage layout has been allowed to retain its glory. Designed by A. W. Tillinghast in 1918, the course is still only 6243 meters long, and it preserves the pioneering architect's vision. The parkland layout proceeds among evergreen groves. The bunkers both follow the contours of the holes and determine how they are played; good scores are dependent on planning and judicious selection of clubs. The seventh hole is known both for being one of which the designer was especially proud, and as the location for the last duel to be fought in the US before the practice was outlawed.
